CONSTRUCTION OF INJECTION-SYRINGES.

To all whom t may concern.'

Be it known that I, JOSEPH BUHLER, M. D., of the city, county, and Stateof New York, have invented a new and useful Instrument for the Treatmentof Diseases of the Generative Organs of Females; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawing', forming part of thisspecification,

Vwhich represents a central longitudinal section of the instrument.

This instrument is to be employed in the treatment of syphilis or anydiseases of the womb.

1t consists of a glass cylindrical receiver A, open at one end andclosed at the other by a metal head B, to which is attached anexhausting pump C, and a force pump D. The exhausting pump C, isconstructed with a solid piston c, and without valves and is providedwith a simple cock a, to open and close the passage b, communicatingwith the cylinder. The force pump D, has a solid piston d, and has astraight passage e, communicating with the receiver A, and from thisstraight passage, a passage f, branches off to the suction pipe It,which should be of india rubber or other flexible material. At thejunction of the passages e, f, there is a three way cock g, having astraight passage 1, directly through it and a passage Qbranchingtherefrom to one side. The head B, is provided with a screw nozzle atthe mouth of the passage c, to receive a mouth piece z', of any desiredform.

The operation of the instrument is as follows: To prepare it for use,the cock a, is opened and the cock g, turned to close all communicationfrom the receiver either to the force pump or to the atmosphere, asshown in the drawing', the position of the cock being determined bystops on the outside, and the piston c, of the exhausting pump requiresto be pushed up as far as possible toward the receiver A. The receiverA, is then inserted into the vagina and vthe piston c, of the exhaustingpump, is drawn out by hand to exhaust the air from the receiver whichcauses the neck of the uterus and the surrounding parts to be drawn upso -far into the receiver as to bevisible to the eye of the medicalattendant through lthose parts of the receiver and to close the passagef.

the sides of the receiver which are outside the body. This being done,the cock a, is closed, and the medical attendant is enabled to ascertainthe nature or state and exact seat of the disease. When this is done,medical applications are made by the force pump in the following manner.The balsain or other medicinal preparation is drawn through the suctionpipe into the pump by drawing out the piston cl, while the cock g,remains in the position shown in the drawing, andv after this the cockis turned to bring the passage l, in line with the passage 2, to opencommunication from the pumlp to ow by forcing in the piston cl, towardthe receiver, the medicinal preparation is injected through the mouthpiece z', to the seat of disease. If washing of the parts be necessary'before applying the medicinal preparations, this may be done by dippingthe nozzle of the suction pipe 7L, in water turning the cock g, to openthe passage f, to the force pump, filling the force pump and thenturning the cock to close the passage f, and open the passage c, fromthe pump to the receiver, and afterward working the piston (Z, back andforth for some time. The water thus used in washing is afterward drawnback into the pump, and finally expelled through the suction pipe it, byproperly turning the cock and forcing the piston toward the passage e.Vashing in this way may be several times repeated with fresh water, ifnecessary. During the operation of washing and applying the medicinalpreparations, the cock a, of the exhausting pump has remained closed,but after the application of the medicinal preparations, the cock a., isopened and the piston c, is pushed in to allow the womb and surroundingparts to return to their' places.

l do not claim any of the parts of this apparatus separately, but

lhat I claim as my invention and desire to secure by Letters Patent, is,

The combination of the receiver A, and pumps C and D, provided withcocks a, and g, in the manner and for the purpose herein set forth.
